Embodiment 1

[0019] Embodiment 1, a topology generation algorithm of a station area, which is completed by the following process: (1) Taking the time of the main sensing terminal as the reference time, and synchronizing the network time with the subordinate sensing terminal through the network protocol; (2) After time synchronization , all nodes start to collect and freeze the real-time current of the line at the same node at the same time point on the time axis, so that each node generates a series of numerical sequences including timing, node position, and current vector value; (3) each node will The above numerical sequence is uploaded to the main sensing terminal; (4) The main sensing terminal converts the numerical sequence uploaded by each node into a time-series complex curve; (5) Extracts the characteristics of the time-series complex curve with a pattern recognition algorithm; (6) Inheriting the relationship with inverse features , to generate a power supply network topology tree. ...

Embodiment 2

[0020] Embodiment 2, a kind of platform topological structure generation algorithm, it is completed by the following steps:

[0021] Step 1: Perform complex processing on the current data collected by a certain node; the real part is the magnitude of the current multiplied by the cosine value of the angle between the voltage and the current; the imaginary part is the magnitude of the current multiplied by the sine value of the angle between the voltage and the current, form a binary number;

[0022] Step 2: Combine the current complex numbers sequentially collected by a certain node on the time axis, according to the time sequence, and according to the fixed time interval, to form a time series current vector sequence (IQ);

Abstract

The invention relates to a transformer area topological structure generation algorithm, which is completed by the following processes of (1) performing the network time synchronization with a lower-level sensing terminal via a network protocol by taking the time of a main sensing terminal as the reference time; (2) after the time synchronization, enabling all the nodes to start to collect and freeze the real-time current of the node line at the same frequency at the same time point of the time axis to enable each node to generate a string of numerical value sequences containing the time sequences, node positions and current vector values; (3) enabling each node to upload the numerical value sequence to the main sensing terminal; (4) enabling the main sensing terminal to convert the numerical value sequence uploaded by each node into a time sequence complex curve; (5) extracting the features of a time sequence complex curve by using a pattern recognition algorithm; and (6) generating a power supply network topological structure tree according to the inverse feature inheritance relationship. The method has the advantages that the power grid basic information mastering capacity is improved, and the technical support is provided for improving the high-quality service levels of the companies.

Description
